Gravitational force is generally the force of gravity. These forces are attractive and dormant in nature. It determines the motion of stars, galaxies, planets, and moons. Whereas nuclear forces play a vital role in the structure of matter, and they act over a short-range. These forces help in determining the stability of nuclei.

The relative strength of the gravitational force is of the order of,${10}^{-38}$whereas the relative strength of the strong nuclear force is 1.

Determine the ratio of gravitational force to the strong nuclear force as:

$$\begin{gathered} \frac{F_g}{F_{N,s}}=\frac{{10}^{-38}}{1} \\ ={10}^{-38} \end{gathered}$$

Here,$F_g$is the gravitational force, and$F_{N,s}$is the strong nuclear force.

Hence, the strength of gravitational force relative to strong nuclear force is ${10}^{-38}$.

The relative strength of the weak nuclear force is${10}^{-13}$.

Determine the ratio of gravitational force to the weak nuclear force as:

$$\begin{gathered} \frac{F_g}{F_{N,w}}=\frac{{10}^{-38}}{{10}^{-13}} \\ ={10}^{-25} \end{gathered}$$

Here,$F_{N,w}$is the weak nuclear force.

Hence, the strength of gravitational force relative to weak nuclear force is ${10}^{-25}$.

Electromagnetic forces are long-range forces that act over large distances. These forces can be attractive or repulsive in nature.

The relative strength of the electromagnetic force is 10^-2.

Determine the ratio of gravitational force to the electromagnetic force as:

$$\begin{gathered} \frac{F_g}{F_{electric}}=\frac{{10}^{-38}}{{10}^{-2}} \\ ={10}^{-36} \end{gathered}$$

Here,$F_{electric}$ is the electromagnetic force.

Hence, the strength of gravitational force relative to electromagnetic force is ${10}^{-36}$.
